Los Angeles -LRB- CNN -RRB- -- Two charges against Chris Brown were dropped Tuesday , but the singer is still accused of hit and run after a minor traffic crash .

Brown 's lawyer entered a not guilty plea on his behalf and a judge ordered him to show up at a sheriff 's station within a week to be officially booked on the charge , according to a court spokesman .

The prosecutor dismissed charges of driving without a license and driving without proof of insurance during a hearing Tuesday in a Van Nuys , California , court .

Brown allegedly sped away from the accident scene in May after a confrontation with the driver of another car , having refusing to provide his name , driver 's license and insurance information .

The hit and run charge threatens Brown 's freedom since it led a judge to revoke his probation last week in connection with his conviction in the beating of his girlfriend , Rihanna . The judge allowed Brown to remain free until a trial is held .

A Brown representative said last week that the singer expected all of the charges to be dropped and probation reinstated this week .

Brown , 24 , was already facing a probation violation trial after prosecutors accused him of not completing the community labor ordered for his 2009 felony assault conviction .

Brown was ordered to return to court on August 16 for a hearing to set a trial date to determine if the probation revocation will stand . If it does , Los Angeles County Superior Court Judge James Brandlin could order Brown to jail to serve part of the original five-year jail sentence imposed for the attack on Rihanna .

A woman whose Mercedes was allegedly rear-ended by a Range Rover that Brown was driving on a Los Angeles street told investigators that he `` went ballistic '' after the traffic accident and screamed at her .

According to the police report on the incident , the other driver , Olga Gure , quoted Brown as shouting at her : `` You are a b -- h ! ''

The report added more from Gure , who quoted Brown as saying , `` Who do you think you are , b -- h ? Do you think if you driving Mercedes so got money , b -- h ? Do you think I am just a black n -- r ? I got more money than you , b -- h ! ''

The trigger for Brown 's alleged rage was that Gure took a photo of him and his girlfriend , Karrueche Tran , to document the scene -- since he allegedly refused to show her his driver 's license , she said .

When Brown tried to grab the camera , Tran screamed , `` Do n't touch her , do n't touch her , '' Gure said .

`` I was so shocked that I was speechless , '' she said . `` Just a moment ago he was a nice guy . After screaming some insulting nonsense for a while longer , he slammed a door and drove away fast and noisy . ''

Brown 's Twitter defense

Brown used his Twitter account to protest the traffic charges last month :

`` It 's not a hit and run if u get out the car , exchange information -LRB- who has NO DAMAGE to either cars -RRB- . This is really ridiculous ''

`` I have a valid drivers license and I gave the woman the right info . She saw cameras and wanted to make a scene . ''

`` She contacted the cops thinking of a payday from Chris Brown when I followed the proper procedures . ''

`` My lawyers will be contacting you . I will not stand for this bullying and yellow journalism ! ''

`` My profile pic is the pic I took of the persons car after `` the hit and run '' . NO damage . Just a dirty car . once again , I got ta clear my name ''

`` I work my ass off to provide for my entire family . I 've made mistakes in the past and have worked hard to be a better person . ''

`` 19-24 years of age . I do n't have all the answers and you ca n't show me a person that age who has it figured out . We live and grow . Let me live ''

Other probation violation charge

Brown punched Rihanna inside a rented Lamborghini on a Hollywood street , leaving her face bruised and bloody on the eve of the Grammy Awards in February 2009 .

He entered a guilty plea seven months later and was sentenced to serve five years ' probation and to spend more than 1,400 hours in `` labor-oriented service '' for the assault conviction . The judge allowed him to serve the sentence in Richmond , Virginia , under the direct supervision of the police chief .

In a court filing in February 2013 , prosecutors accused Brown of not completing the community labor . The paperwork Brown submitted to show he had completed community labor is `` at best sloppy documentation and at worst fraudulent reporting , '' District Attorney Jackie Lacey said . Brown was n't in town on some of the dates reported , the motion said .

Geragos , Brown 's attorney , said the prosecutor 's filing was so fraudulent that he would ask the judge to punish the deputy district attorneys involved and call for a contempt of court hearing for filing false documents with the court .

`` And I do n't mean just false , it is fraudulent , '' Geragos said .

The Los Angeles County district attorney 's office has `` tortured '' Brown during his probation more than any client he 's ever had , Geragos said .

The prosecutor is asking the judge to order him to restart his 1,400 hours of community service under the supervision of a Los Angeles probation officer .
